Sarah is a crypto economist who spent seven years building cross-border payment products at two African fintech unicorns before bringing her real-world payments expertise to DeFi. She holds an MSc in Financial Economics from the University of Oxford and specializes in the economics of cross-chain transfers — how fees, slippage, liquidity depth, and route selection affect what actually lands in a user's wallet. Her bridge fee comparison methodology has been adopted by three crypto media outlets as their standard benchmarking approach.

Sarah's obsession with payment efficiency didn't start with crypto. It started with remittances. At her first fintech role in Lagos, she watched users pay 8-12% in fees to send money across borders — money that families needed for school fees, medical bills, and rent. She spent five years building products that brought those costs down to under 2%, serving over three million users across Nigeria, Kenya, and Ghana. When she discovered stablecoins on Tron in 2022 — where transfers cost fractions of a cent — she realized blockchain could compress remittance costs further than any traditional fintech stack ever could.

That insight drives her work at MoveCrypto. Sarah doesn't just write about bridge fees; she built the methodology that makes those comparisons rigorous. Her approach is deceptively simple: execute identical transfers across multiple bridges under the same market conditions, record the exact input and output amounts down to the satoshi, and publish everything — including the timestamps, the slippage, and the gas costs at the moment of execution. No cherry-picking. No "up to" claims. The raw CSV data lives on MoveCrypto's site for anyone to verify. Crypto media outlets including three major publications now use her methodology as their standard for bridge fee reporting.

Sarah leads content strategy and market research at MoveCrypto, where she writes the bridge fee comparison studies, regulatory analysis, and payment guides that consistently rank among the site's highest-traffic pages. Her coverage of the GENIUS Act's implications for stablecoin payments was cited by two policy research organizations, and her freelancer payment guides have become go-to resources in the Web3 freelance community.

She is a vocal advocate for crypto adoption outside the Global North and writes regularly about how stablecoins and cross-chain infrastructure solve real problems for real people — not just degens chasing yield. "The metric that matters," she often says, "isn't TVL. It's how much money actually reached someone who needed it."
